| Intelligent Entrance Guard System is a new kind of modern security system which is based on automatic microcomputer identification technology and modern security management. There are many new technologies are used in this system, it relates to electricity, mechanics, optics, computer technology, communication technology and biologic technology. Intelligent Entrance Guard System is an effective solution to the entrance security management of some important department. It has widely use in varies important department such as bank, hotel, control room, armory, office, intelligent housing estate and factory. It plays an important role in workplace safety, personnel attendance management and other administrative works.Currently,there are many different Entrance Guard System existed, each with its own advantages and disadvantages. We give a design of an Intelligent Entrance Guard System in this paper, which is based on embedded system technology and SEP4020, and designed for the environment with high security requirements. The design includes hardware design and software design. The hardware design includes information storage, processing, storage, and communication. Use the entrance guard system management software, for all the controller unit for centralized management and monitoring, and through the SQL database according to the relationship between the structure of the data organization, storage, and all the data and information management system, finally according to the different methods of communication can be selectively implement device and network communication control.This Intelligent Entrance Guard System has been tested in the late stages of development and design now, and will soon go into production, used in the community. |
